MAGMA COPPER CO. ANNOUNCES FATALITIES AT SUPERIOR MINING DIVISION

 TUCSON, Ariz., Aug. 11 /PRNewswire/ -- Magma Copper Co. (NYSE: MCU) today reported an ore slide in one of the ore passes at Magma Copper Co.'s underground mine in Superior, Ariz., (60 miles east of Phoenix) has resulted in four fatalities. There were no other injuries.
 Dead are John H. Dalton, 38, of Miami, Jeff Christiansen, 21, from Claypool, Alfred Edwards, 56, of Globe, and Nicholas P. Truett, 19, from Superior. Dalton was a group leader, Edwards a team leader and Christiansen and Truett were support technicians at the mine.
 According to Doug McGregor, general manager of the mine, the accident occurred sometime between 9:30 p.m. and 11 p.m. yesterday.
 "We are deeply saddened by the loss of life and are making every effort to compassionately respond to the needs of the victim's families," McGregor said.
 "We and officials from the Mining Inspector's Arizona office and from the Mine Safety and Health Administration are trying to reconstruct how the accident occurred. Apparently, ore that was hung up in the ore pass somewhere between the 3,600- and 4,000-foot level gave way. The men were performing maintenance work in a `manway' adjacent to the ore pass, attempting to dislodge the blockage. The exact location of the men at the time the ore became dislodged is not known.
 An ore pass is a conveyance down which copper ore is dropped to rail cars below and then transported out to the main shaft for hoisting.
 "It appears the men were unaware that the ore became dislodged while they were working. The sudden impact of approximately 50 to 60 tons of ore took out approximately 150 feet of the timber and steel retaining wall that separated the manway from the ore pass," McGregor said. As a result, they were buried beneath the ore and timber rubble.
 Both Dalton and Edwards were supervisory-level employees with more than 50 years of mining experience between them. The mine had received a clean inspection within the last month from the Mine Safety and Health Administration.
